SPECIFICATION forming part of Letters Patent No, 307,4:93, dated November 4, 1884.

Application filed March 3, 1884. (No model.)

Be it known that I, ALFRED B. REEvEs, a citizen ofthe United States, residing at Columbus, in the county of Bartholomew and State of Indiana, have invented certain new and useful Improvements in Cultivators, of which the following is a specification.

My invention relates to improvements in that class of cultivators known as tongueless straddle-row twohorse cultivators.

The objects of my improvements are to provide an improved support for the cultivatorplows when raised out of the ground, an improved draft attachment, and an improved socket for attaching the plows-to their standards, all as hereinafter described.

The accompanying drawings illustrate my invention.

Figure l is a side elevation showing the plows in position for work. Fig. 2 is a side elevation showing the plows raised. Fig. 3 is aperspec tive view of the draft attachment. Fig. 4 is a side elevation of one of the plows and its standard. .Figs. 5 and 6 are plans of the same, the standard being shown in section.

a represents the draft-beam of the plow-gan g. Said beam is pivoted at its forward end to a clevis, b, so as to swing vertically thereon, and said clevis is secured to the arched connecting-bar c.

d is a short arm projecting from the front part of clevis Z2.

c is a bent bar pivoted to arm (I, and forming a support for the draftbeam a when said beam is raised out of working position. Said bar has a short arm, f, adapted to receive and support the d raft-beam a, and a longer arm, 5 adapted to rest upon and slide along the surface of the ground as the cultivator is drawn forward.

It is a bar rigidly secured to beam a, projecting forward and downward therefrom, and having its forward endprovided with a pin, '17, or otherwise so formed as to engage the un der side of bar a. When the draft-beam is aised and rests upon the short arm f of bar 0, as shown in Fig. 2-, the lower part of said bar rests on the ground, and thereby sustains the plow-beam in its elevated position, and also, through the connection of the plow-beam and said bar with clevis b, prevents the arch from tipping backward. Then the plow-bean1 is disengaged from arm f, as said beam swings downward, the forward end of bar it is raised, carrying upward at the same time bar 6 into the position shown in Fig. 1. The draft attachment is formed of two flat bars of wrought iron, 3' and k. Barj is bent at right angles to form a standard, or, to which the axle a is bolted, and onejaw of a clevis, Z. Said bar j is then beat upward at an acute angle, as shown, to form one jaw of a clevis, 0. Bar is is lighter than bar and said bars j and 7c are riveted or otherwise rigidly secured together at 1), bar It being bent outward, as shown, to form with bar j the clevises Z and 0. Glevis l embraces and is pivoted to the arch-bar c, and clevis 0 receives the singletree, to which the draft animal is attached.

q, Figs. 5 and (5, represents the lower portion of one of the plow-standards.

1- represents the plowshare, and s the socket by which the plowshare is secured to the standard.

For the purpose of providing for the adj ustment of the plows on the plow-standards, I make the standard of the same rectangular section throughout, and form the socket s with an angular eye, i. That side of said eye next the plow is made wider than the other, the narrow side being only wide enough to receive the edge of the standard q, andthe other side being wide enough to allow the plow to be swung to either side or fastened centrally by a set-screw, a, in the narrow side of the socket, as clearly shown in Figs. 5 and 6.

I am aware that tapered shovel-sockets for securing the shovel or plow to its standard, and having the narrow side of the socket next the plow, and a set-screw in a movable nut in the wide side of the socket have before been made, and I do not claim such a device.

I claim as my invention- 1. In a cultivator, the combination, with a beam-coupling, a plow-beam hinged vertically thereto, and a bent bar pivoted to said coupling, so as to swing vertically thereon, and adapted to rest on the ground at one end and to support the free end of said plow-beam at the other, of bar h, rigidly secured to said plow loeam and adapted to engage and raise said bent bar, substantially as specified.

2. In acultivator, the above-described draft the wide side of said eye next the plow, and I0 attachment,consisting of barsj and 7c, bent and set-screw u, having its nut formed in the nar joined as shown and described, and forming l row side of said eye, all substantially as and an axle-standard and adoulole clevis, substanfor the purpose specified. tially as and for the ur oses specified.

3. Ina cultivaton the combination, with a ALFRED REEVES plow and a plow-standard of substantially rect- WVitnesses: angular section, of socket 8, having an angular l M. J. GALVAN, tapered eye, t, and secured to the plow with M. T. REEVES.
